Definitions

  • the invention relates to an arrangement of protective bars on the tine rotors for multi-rotor tedders according to the preamble of claim 1.
  • the invention has for its object to arrange the protective bracket or to bring it into such a pivoting position that when the rotary tedder is switched from the working to the transport position without having to carry out dismantling work, neither with the machine frame nor with the other protection bars collide.
  • a rotary tedder (1) shown in the drawing with eight tine rotors arranged on support arms is pulled and driven by a tractor (2).
  • a drawbar (4) and a connection (5) for an articulated shaft (6) to the gearbox of the tractor (2) are arranged on the front of a rigid longitudinal beam (3) running in the direction of travel (F).
  • the drawbar (4) is connected to the two-point hitch (7) of the tractor (2).
  • a cross member (8) is arranged at the rear end of the longitudinal member (3). Connected to the crossmember (8) on both sides are a plurality of support arms which can be swiveled forward about approximately vertical swivel axes (9, 10) with tine rotors arranged thereon.
  • Two central tine rotors (11, 12) are arranged on the crossmember (8) and one tine rotator is arranged on each of the support arms.
  • the individual tine rotors are driven from the tractor (2) via the cardan shaft (6). From there, the rotary movement is forwarded via a drive shaft arranged below the longitudinal beam (3) (13) to the input gear (14) on the cross member (8).
  • Shafts running on both sides within the crossmember (8) adjoin the input gear (14) and lead to the gyroscopic gears (15, 16) of the rigidly connected middle tine rotors (11, 12).
  • the cross member (8) is provided with two height-adjustable transport wheels (17, 18) which are attached below the tine rotors (11, 12) and which are in constant contact with the ground in the working and transport position. Probe wheels (19) are arranged below the other tine rotors.
  • First lateral support arms (20, 21) adjoin the cross member (8), on which the first lateral tine rotors (22, 23) are arranged. The support arms (20, 21) can be pivoted up and down about horizontal pivot axes (24, 25) attached to the cross member (8).
  • first lateral tine rotors (22, 23) are connected to the second lateral tine rotors (28, 29), which are attached to second lateral support arms (30, 31) and connected to the rotary drives (26, 33) via horizontally arranged swivel axes (32, 33). 27) of the first lateral tine rotors (22, 23) are connected in terms of drive.
  • the outer tine rotors (34, 35) which are connected to it in an articulated manner are attached to outer support arms (36, 37). Between the first side support arms (20, 21) and the outer support arms (36, 37) hydraulic cylinders (38) are arranged, with which the pivoting of the outer tine rotors (34, 35) about the associated horizontal pivot axes (39, 40) and the second lateral tine gyro (28, 29) about the pivot axes (32, 33). The lateral and outer tine rotors (22, 23, 28, 29, 34, 35) are swiveled from the working to the transport position and vice versa about the vertical swivel axes (9, 10), which have a forward inclination angle.
  • Single-acting hydraulic cylinders (41, 42) are arranged between the side member (3) and the first side support arms (20, 21).
  • the side and outer tine rotors (22, 23, 28, 29, 34, 35) pivoted from the transport position into the working position.
  • the vertical swivel axes (9, 10) inclined forward by approximately 15 ° the raised lateral tine rotors (22, 23) automatically swivel forward by approximately 90 ° after interrupting the pressure oil supply to the hydraulic cylinders (41, 42) and thereby get into a transport position running parallel to the side member (3).
  • protective bars are arranged in the working position in front of the rotating tine rotors over the entire working width, which are brought into a space-saving position in the transport position, in which they do not hinder the pivoting process and with the side member (3) of the machine frame and with the neighboring protective bars collide.
  • protective brackets (43, 44) are arranged in front of the first lateral tine rotors (22, 23), which are rigidly attached to holding arms (45, 46).
  • the holding arms (45, 46) are pivotally connected to the housings of the rotary drives (26, 27) of the first lateral tine rotors (22, 23) via vertically arranged articulated axes (47, 48).
  • Coupling rods (49, 50) are attached to the end of the protective bracket (43, 44) facing the side member (3), the other ends of which are articulated on the side member (3).
  • the ends of the coupling rods (49, 50) are connected to the protective brackets (43, 44) or to the side member (3) by means of gimbals (51, 52, 53, 54).
  • This articulated design enables the vertical, longitudinal and inclined displacements of the respective articulation points that occur when lifting and swiveling the lateral and outer tine rotors (22, 23, 28, 29, 34, 35) upwards and forwards.
  • the coupling rods (49, 50) also act as protective bars for the middle tine rotors (11, 12).
  • the protective brackets move (43, 44) and the associated coupling rods (49, 50) automatically in such a space-saving position above and in front of the tine rotors (22, 23), in which there is no contact with the side member (3).
  • the lateral tine rotors (22, 23) can be pivoted into an approximately parallel position to the longitudinal beam (3), resulting in a small transport width of the rotary tedder (1).
  • Another possibility for pivoting the protective bracket (43, 44) is that a control rod articulated on the side member (3) is pivoted upward about a horizontally arranged pivot axis.
  • the vertical swivel axis of the protective bracket (43, 44) must be replaced by an approximately horizontal swivel axis.
  • the second lateral tine rotors (28, 29) are assigned separate protective brackets (55, 56) that are firmly connected to them. In order to avoid a mutual collision of the protective brackets (55, 56) during the pivoting process of the tine rotors (28, 29), these are arranged offset in height from one another.
  • External protective brackets (57, 58) are attached to the outer tine rotors (34, 35), which are rigidly connected to the tine rotors (34, 35) and are also offset in height from each other to avoid a risk of collision when the tine rotors (34, 35) are pivoted into the transport position are arranged.
